DISPENSING DEVICE.

Specification of Letters Patent.

Patented July 3, 1906. I

Application filed July 3,1905. Serial No. 268,132-

T all whom it may concern/.-

Be it known that I, THEODOR KURRELL, a citizen of the United States, residing at St.. Louis, State of Missouri, have invented certain new and useful Improvements'in Dispensing Devices, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention has relation to improvements in dispensing devices for semiliquid or plastic substances, such as mustard, salvcs, pomades, soaps, vaseline, sauces, and the like; and it consists in the novel construction and arran gcment of parts more full set forth in the specification, and. pointed out in the claims.

In the drawings, F igure 1 is an elevation of the device with wall partly broken away. Fig. 2 is a middle vertical section on line 2 2 of Fig. Fig. 3 is a top plan view. Fig. 4 a horizontal section on line 4 4 of Fig. 2. Fig. is a horizontal section on line 5 5 of Fig. 2, showing the parts in normal position. Fig. 6 is a similar section showing the actuating camdisk turned to a position to open the slide valve or gate, and Fig. 7 is a vertical sec- The present device, though specially designed for dispensing mustard at the dinnertablc, may be used for dispensing predetermined quantities of any plastic or semisolid 1 substances on the order above specified. Its l obiect is to retain the mustard in a receptacle from which the is excluded, so that it may remain permanently fresh.

A further object is to dispense with the use of spoons and with the necessity of serving the same from a. spoon.

A further object is to prevent smearing the mustard unnecessarily over surfaces where it is not desirable and, in fine, to provide a re ceptacle from which the material Ina Y be dispensed with cleanliness and in definite quantities.

.ln. det as follou 1: Referring: to the drawings, 1 represents a suitable holder or receptacle provided with a cover or screw-top 2, which serves as a sup? port for the upper end or spindle3 of the ceni 'ii operating screw 4, the lower spindle 5 of ng loosely through a central. e bottom of the receptacle and crmina' n "1 red used end or extension 5".

the invention may be described which '1. socket in the bottom of too realm. screw oi-.se or bottom 6. Se-- tween the bottom ol the receptacle and the base 6 is a chamber 7 for the housing of a portion of the opcrating'parts of the device. a suitable dischargc-tulie 8 lcading from the recePtaclc-bottom to a dischargc-opcning ll of the scrcw base. Passed over the spindle 5, which is flattened on one side, is the hub portion of a cam-disk 10, the flattening referred to preventing rotation of the cam about the spindle. The cam-disk is provided with a V-shapcd recess 11, to the base of which is normally forced and held a pin 12 by the resilient action of the terminal arm of a spring 13, whose fixed end is secured to a post 14 on the screw-base 6. The pin 12 is scoured to a sliding gate or valve 15, which controls the discharge end ol the tube 8, the gate having formed therein an elongated slot ofor the passage therethrough of the spindle 5 and to allow for the necessary rcciprocations of the gate, as will moreiully hereinafter appear. The gate has an upturned wall or end 15', against which the spring-arm 13 bears, tending to always force the gate to its closed position-that is, over the discharge end of the tube 8. The gate guided within grooves or ways formed or channeled out from the floor of the base 6, Fig. 7. Adapted to travel along the screw 4 is a follower or piston 16, capable only of longitudinal motion on the screw, but not capable oi r. .ation aboul its axis. The upper spindle of the scrcw is provided with a milled head 17, below which is secured an arm 15, cooperati Hg with an indexmark 19, from which as a starting-point the arm marks a complete revolution for a. single rotation of the screw and for an advance or the piston 16, corresponding to a single discharge of the material forced through the opening 9.

The operation of the device is as follows: By removing the screw top or cover '2 the screw 4, with its follower 16, may be withdrawn and the receptacle filled with the material M to be dispensed. The parts are then replaced and the scie-\'-t )p secured in place. Normally the gate 15 is c osed over the discharge-opening 9, being held in said. closed position by the spring 13, the pin 12 on the gate for the closed position of the latter oc cupying a position at the base or" the recess 11, Fig. 5. By turning the milled head 17 in the direction shown by the arrows in Figs. fiend lithe pin 12 rides along the cam edge of the disk 10, the eccentric formation of such edge forciiig the pin lland gate 15 IIO outwardly, thus uncovering the opening 9 at the bottom of the tube 8, Fig. 6. At the same time the follower or piston 16 is de scending along the screw 4, and in. its descent it forces or expels the contents of the receptacle through the 'tube 8 anddischarge-opening 9. The discharge of the material will continue as long as the screw 4 is turned and as long as the opening 9 is uncovered. By the time the screw makes a complete revolution (by which time the arm 18, which initially started from the mark 19, will again come opposite said mark) the resiliency of the spring 13 will suddenly ftrce the gate to its closed position, driving the pin 12 to the base of the recess 11 along the radial edge of said recess. The parts are thus brought back into their original position, when a secnd turn of the screw Wlll force another portion of the contents through the opening 9. This can be repeated until the follower 0r piston 16 has been driven to the bottom of the receptacle, by which time it will have forced outth'e entire contents thereof.

Obviously 'I may depart in minor details of construction without affecting either the nature or spirit of my invention.

Having described invention, what. I claim is v 1. In a dispensing. device ofj'the class described, a suitable receptacle, a follower therein, means for actuating the follower, a valve-controlled discharge opening leading from the receptacle, and means for uncovering said opening upon movement of the fol? lower against the contents of the receptacle, whereby said contents may be expelled by said follower, substantially as set forth.

2. In a dispensing device of the class described, a suitable receptacle, a follower '7 movable against the contents thereof, means for actuatin the follower, a discharge-opening leading from the receptacle, a gate normally closing said opening, and means for shifting said gate and uncovering the opening with the ex el'ling movement of the follower, substantially as set forth.

3. A dispensing device of the class described comprising a receptacle, a screw passcentrally through the same, a piston or fo lower on the screw, a chamber at the-base of the receptacle, a spindle forming the lower extension of the screw and entering said chamber, a cam-disk mounted on the spindle, said disk having a eripheral recess, a

sliding gate mounted at t e base of the cham her and controlling a discharge-opening from the receptacle, a springbearing against the gate and normally forcing the same to a '4. In a dispensing device of the class de scribed, a suitable receptacle, a screw passing centrally through the same, a piston or follower on the screw, a discharge-opening leadspring-controlled gate normally closing said opening, and intermediate connections between the screw and gate for shifting the gate to open position upon a. turning of the screw for the expelling movement of the follower, I

substantially as set forth.

' 5., In a dispensing device of the class de; scribed, a suitable receptacle, a screw passing through the same, a piston or follower on .the

screw, a discharge-opening leading from'the' bottom of the receptacle, a sprin -controlled reciprocating gate normally 0 osing said opening, and intermediate connections between the screw and gate for shifting the gate ing from'the bottom of the receptacle, 3..

to open position upon a turning of the screw for .the expelling movement of the follower,

substantially as set forth.

In testimony whereof I affixmy signature in presence of two witnesses. v

THEODOR KURRELIJ.
